Application filed March 10, 1914. ISerial No. 823,781.

To all 'Lo/wm t may concern:

Be it known that l, WILLIAM J. CASSITY, a single man, a citizen of theUnited States, residing` at Guthrie, in the county of Logan and State ofOklahoma, have invented new and useful Improvements in Stump-Burners, ofwhich the following is a specification,

The invention is primarily vintended to provide novel means for removingstumps by lire when clearing land for agricultural purposes.

|The invention provides an appliance which is portable, economical inconstruction and effective in use, the same serving to remove bothseasoned and green or unseasoned stumps by fire.

The invention consists of a hollow body or casing adapted to be placedover the stump to be consumed, said casing resting upon the ground andbeing provided with a removable top and draft inlets and smoke outlet.

rllhe invention consists of the novel features, details of constructionand combina tion of parts, which hereinafter will be more particularlyset forth, illustrated and claimed.

ln the drawings hereto attached :-Figure l is a perspective view of astump burner embodying the invention. Fig. 2 is a vertical centralsection.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing, by the sainereference characters.

The body or casing l is preferably constructed of sheet metal and is ofa shape and size to completely envelop the usual stump. The casing mayhave any outline and as shown is preferably of frusto-conical shape toconform approximately to the outline of a stump. 'l ie bottom of thecasing is open and in practice is adapted to be closed by the groundupon which the burner is placed.I earth being packed around the lowerend of the Vcasing to completely close the same. The top of the casingor hollow body is closed by means of a cover 2 which comprises a top anda depending rim. An opening 3 is formed in the top of the cover 2 and isadapted to be closed by meansof a slide 4 which is mounted in suitableways A pipe 5 is removably fitted in the opening 3 and is suspended fromthe top of the cover and extends within the body or casing to within ashort distance of the lower end thereof. The pipe 5 provides an inletfor air when the burner is used for consuming green or nnseasoned stumpsso as to convey the air to the roots to insure combustion thereof. rfheslide l may serve to regulate the draft through the pipe 5 and alsocloses the opening 3 when the pipe 5 is removed and not required forimmediate use. A smoke pipe 6 connects with the lower portion of thebody or casing l and carries 0E the products of combustion when thedevice is in service. Draft openings 7 are provided in the lower portionof the body or casing l and are adapted to be regulated by means of adamper 8 which is slidably mounted in ways or guides.

When the device is used for burning seasoned stumps the pipe 5 isremoved and the opening 3 is closed by means of the slide 4. The body orcasing is placed over the stump to be burned and the cover 2 is placedin position. Kindling is placed within the body or casing at the base ofthe stump and is lighted, after which the damper 8 is moved to uncoverthe draft openings. lThe stump having been lighted is graduallyconsinned, after which the device is removed and again placed inposition for burning another stump. in the event of the stump beinggreenV the roots are consumed after the body of the stump has beenburned by placing the pipe 5 in position and closing the damper 8thereby causing the draft to enter the pipe 5 and be delivered directlyupon the roots which are thus consumed.

From the foregoing description, taken in connection with theaccompanying drawing the advantages of the construction and of 'hemethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of theinvention as claimed.

Having thus described the invention, what is claimed as new is A. stumpburner comprising a casing of frusto-conical shape, the same having adraft opening therein, a damper for conn cev trolling said draftopening, a smoke pipe being n'alinement in close proximity to theconnected with the lower portion ofthe easlower edge of the casing. l0ing, a cover closing the top of the casing In testimony whereof I affixmy signature having an opening' therein to one side of a in presence oftwo witnesses.
